The power generation industry is undergoing a dramatic change as renewable sources, distributed generation, decarbonization, and demand increases are transforming traditional energy management. Data centres can participate in this transformation, leveraging UPS and battery assets to support a variety of grid-balancing services that yield new revenue streams and cost savings. While the availability, safety, and scalability remain data center essentials, sustainability goals are driving a wave of innovation that is allowing operators to make significant gains in the utilization and efficiency of critical power infrastructure.
